This specification covers twelve grades of thermosetting laminate with copper foil cladded to one or both surfaces. These combination forms are intended primarily for use in fabrication of printed (etched) wiring or circuit boards. The laminates shall meet the following requirements: peel strength after solder float and at elevated temperature conditions; lengthwise and crosswise flexural strengths; flammability rating; water absorption; volume resistivity; dielectric breakdown parallel to laminations; dissipation factor; and permittivity. Warp or twist, and blistering requirements shall also be tested for conformance.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope
